Intent的几种用法

Intent的几种用法

【转载】学习笔记


Intent应该算是Android中特有的东西。你可以在Intent中指定程序要执行的动作（比如：view,edit,dial），以及程序执行到该动作时所需要的资料。都指定好后，只要调用startActivity()，Android系统会自动寻找最符合你指定要求的应用程序，并执行该程序。

下面列出几种Intent的用法
显示网页:

1. Uri uri = Uri.parse("http://www.google.com");

2. Intent it = new Intent(Intent.ACTION_VIEW,uri);

3. startActivity(it);

复制代码

显示地图:

1. Uri uri = Uri.parse("geo:38.899533,-77.036476");

2. Intent it = new Intent(Intent.Action_VIEW,uri);

3. startActivity(it);

复制代码

路径规划:

1. Uri uri = Uri.parse("http://maps.google.com/maps?f=d&saddr=startLat%20startLng&daddr=endLat%20endLng&hl=en");

2. Intent it = new Intent(Intent.ACTION_VIEW,URI);

3. startActivity(it);

复制代码

拨打电话:
调用拨号程序

1. Uri uri = Uri.parse("tel:xxxxxx");

2. Intent it = new Intent(Intent.ACTION_DIAL, uri);

3. startActivity(it);

复制代码

1. Uri uri = Uri.parse("tel.xxxxxx");

2. Intent it =new Intent(Intent.ACTION_CALL,uri);

3. 要使用这个必须在配置文件中加入<uses-permission >android.permission.CALL_PHONE" />

6.

7. //显示指定应用的详细页面（这个好像不支持了，找不到app_id）

8. Uri uri = Uri.parse("market://details?id=app_id");

9. Intent it = new Intent(Intent.ACTION_VIEW, uri);

10. startActivity(it);

11. //where app_id is the application ID, find the ID
